Hi All,

I am planning to write a logic in my application where I want to check for some software installed on client windows machine. If it is not installed then this web application will ask end user to download from web site.

Kindly suggest some logic.

There is no API to get a nice list of installed software, so you have two ways to find it out
1. Check for certain folder/executable that come with the application
2. Read the registry of the machine for uninstall entries to find if software is there: SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall. You should check this branch also under 'LocalMachine' and 'CurrentUser'...
